It may not be because they are less healthy!
It could just be that their intensive workouts are a very poor match for the post-injection condition...
In other words, perhaps the jab is stripping away the protective adaptations their bodies once had - the very thing that helped them deal with intense exercise.
I mean we know that short term intense excercise puts the body in a extremely stressfull situation inlcuding damage to the cells, impairing digestion, draining resources etc.
This short term damage usually comes with the reward of adaption and better utilization of resources, blood flow etc.
It is therefore not unreasonable to theorize if the vaxxine could either cause a impairment to the regeneration, or the other way around, the workout induces a stress burden to much to handle trough the problmens already established by the vaxxine. Going running with alot of clotting sounds bad ... clotting in general sounds bad ...
